HOLDER FOR WIRE-STAPLE BELT-FASTENERS.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application filed October 12, 1917. Serial No. 196,981.

To all whom it may concern:

Be it known that we, JOHN YET'roN and WILLIAM ERNEST Bnocnn'r'r, subjects of the King of Great Britain and Ireland, residing at Marshgate Engineering lVorks, Marshgate Lane, Stratford, London, in the county of Essex, England, have invented new and useful Improvements in Holders for Wire-Staple Belt-Fasteners, of which the following is a specification.

The invention relates to holders for beltfasteners of the kind known as wire staple belt-fasteners.

Holders for wire staple belt-fasteners consist of suitably shaped strips. of metal or other material in which the fasteners are held in assembled position and sold in such.

form. These strips or holders are generally provided with slots, projections or corrugations by means of which the fasteners are guided as they are clenched or secured 7 to the ends of belts. Such slots, projections and corrugations only serve, as the fasteners are being clenched or secured to a belt, as lateral supports for the rear ends and the diverging limbs of the fasteners. Itis however desirable, especially in the case of belts which offer a considerable resistance, that a holder for wire staple belt-fasteners should be such that the inwardly projecting parts of the fasteners, that is to say the parts projecting from the front ends of the diverging limbs of the fasteners, shall be laterally supported during the whole or the greater part of the time that they are being driven or forced into the end of a belt.

According to the present invention holders or carriers for wire staple belt-fasteners are constructed in such manner that not only are the rear bent parts and the diverging limbs of the fasteners laterally supported but also the inwardly bent portions thereof.

As a result of this construction the in-' wardly bent parts of the fasteners will correctly penetrate the substance of a belt, and when the clenching operation is completed all parts of the fasteners will lie in planes coincident with the center lines of the fasteners.

The improved holder may, for example, consist of a strip of metal bent to such shape as to provide five sides or walls which more or less conform to five of the sides of a regular hexagon. Two of the walls of formed with slots.

of the strip are between the walls which serve as abutments for the limbs of the fasteners, serve as lateral supports for the rear bent parts of the fasteners, while the other two sets of slots serve as lateral supports for the front ends of the limbs of the fasteners and the inwardly bent parts of the fasteners. The rear wall of the strip may either beflat or be bent in the direction of the front or open part of the holder.

The accompanying drawings illustrate a holder fulfilling the purposes of thepresent invention and made in the form just described.

Of these drawings, Figure l is an end view of said holder and Fig. 2 is a transverse section thereof, the section being taken through the slots formed in said holder. Figs. 3 and 4 are views corresponding to Figs. 1 and 2 but showing the wire staple belt-fasteners in position in the holder. Fig. 5 is a plan of the strip from which would be formed the holder shown in Figs. 1 to 4.

Referring now to these drawings,-a holder fulfilling the purpose of the present invention preferably consists of a strip of metal which is bent tosuch shape as to provide five sides or walls 1, 2, 3, 4: and 5 which, as will be seen from an inspection of Figs. 1 to 4, more or less conform to the sides of a regular hexagon. Two of these sides or walls 2 and 4E, serve as abutments, see Fig. 4, for the diverging limbs of the fasteners, while the remaining sides 1, 3 and 5 are formed with slots 6, 7 and 8. Of these slots, the slots 6 in the rear wall 3 of the holder servev as lateral supports for the rear bent parts of the fasteners, 9, while the slots 7 and 8 serve as lateral supports for the front ends of the limbs of the fasteners 9 and the inwardly bent parts of said fasteners.

A holder of the shape illustrated by Figs. 1 to 4 would be formed by bending at the proper parts a metal strip such as'shown by Fig. 5, in which the parts at which the strip.

qward'one'anothe'r, secures v 7 Such a rod or pin may. how-- The rear wall 3 .of the holder illustrated V by Figsil' to .4, instead of being straight, as

shown, may be curved orfbent in the direction of the front or openpart of the holder;

A holder of the general form shown-in 'Fig'sl'l t6 4 possesses the advantage that a rod or pin is not necessary-for the purpose of retainingthe fastenersinthe' holder, as

the final bending operation, viz,- that by Whih the Sidesdi Walls -1 and 5 are b'n'tftbthe fasteners within the strip. ever be used.

-V However 1t is desirable dnring'the'opera- Having now described our invention whatv we have invented and desire to secure by Letters Patent of the United States is as fol- 1.- In combination, "a staple having reversely disposed prongs formed thereon, and

can; of patent may be obtained for :bent parts, the bent parts of the fasa holder comprising means for contacting with and preventing lateral movement of said prongswith relation to the shanks on which they are'forined when forcing said staple into any material. V I

. 2. A holder for wire'staple belt fasteners consisting of a strip of metal or other suitab1e'materia1 bent toa shape more or less of. the bent strip, be-

,conforming to five of thesides of a regular 1 hexagon'and provided'with slots in its 'two outermost walls and its rearmo'st wall, the

remaining two walls :40

tween said outermost-and rearmost walls be- I I ing nnslotted, substantially as described.

3. In conr ibination, a staple formed of a single lengthflo'f wire andfconiprising rear divergent limbs "and inwardly bent parts, and holder having terminal slotted portionsreceivin'g and contacting withthe "limbs and the said inwardly bent parts for preventinglateral-displacement of r said inwardly bentparts and-limbs when :the'stap'le isbelng driven into a belt.

' In testimony whereofwe have signed our names to this specification.
